Hi, Im getting this messages in the /var/log/messages about my

case I have to ask. Are these messages fine? Do I need to specify
the interface on which the dhcp server should listen to?
...

What's ifconfig report for the IP addresses and subnet masks of
your multiple interfaces? And are these interfaces in fact cabled
to the same switch/hub?
Thanks
Jean

Yes, the two interfaces are configured to be int he same network
using the same switch and everything; only because this server is
replacing an old server. I guess if this is not an "OK" design I can
just move the dhcp to a new server, since that this would be so easy to do.
You might want to use aliaing, so that eth0 is the base address and
eth0:0 is the IP address of the old server you've pulled out of
service. That way your new server will respond to both addresses, but
without the issues that arise with two interfaces on the same subnet.
The DHCP server will operate without complaint in the presence of
additional IP addresses on a single interface.
